The Claim
Intermittent fasting and caloric restriction reduce circulating levels of insulin-like growth factor 1 (IGF-1) in healthy adults, and a three‑month fasting‑mimicking diet administered in three cycles lowers IGF-1 levels, suggesting this reduction may be a mechanism for decreasing cancer risk because IGF-1 promotes tumor growth and cell proliferation.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Skipping meals or eating fewer calories can lower a hormone called IGF‑1 in healthy people, and doing a special three‑month diet three times does the same, which might help lower cancer risk.
See the scientific wording
Intermittent fasting and caloric restriction reduce circulating levels of insulin-like growth factor 1 (IGF-1) in healthy adults, with a 3-month fasting-mimicking diet regimen lowering IGF-1 levels across three cycles, suggesting a potential mechanism for cancer risk reduction given IGF-1's role in tumor promotion and cell proliferation.
